13、推施工情况和横向1号桥初步设计的情况介绍，说明了日本采用集中式（TL式）顶推预应力连续曲线梁桥的施工工艺和设计特点。 釜户川桥的顶推施工 釜户川桥为双线3连三跨（共9跨）预应力连续梁，下行线跨度为2连340.9m+1连342.4m，上行线跨度为2连342.4m1连340.9m。全桥在半径R1400m的圆曲线上，采用等高度箱形截面。按设计采用顶推法施工，是日本目前顶推施工规模最大的一座桥梁。 一、施工概要 本桥采用集中(TL)式顶推施工，即顶推千斤顶设置在预制节段前方的桥台（或墩）上，集中对桥梁施架顶推力，梁在支点和墩顶上设置的滑动支承上滑动。TL装置有两种方式，即拉杆方式和垂直、水平千斤顶方式
14、（图1）。本桥根据上行线与下行线两者的具体情况，两种方式均采用。上行线中，由于桥台与主梁制作台距离较短，因而采用拉杆方式。下行线中距离较长，由于拉杆伸长带来的损失较大，因而在初期采用拉杆方式而后期用垂直、水平千斤顶方式。图1 TL顶推装置方式 本桥的最大顶推力，考虑滑板支承的摩擦系数、上坡方向顶推的升力、平面线形和横向坡度等因素，达到700吨。因而设置了2台400吨千斤顶。 本桥除在平面上处于R1400m的圆曲线上外，还设有i2.016%4.083%的纵坡和R18000m的竖曲线，横向设有i2.488%3.0%的坡度，使得顶推需要在一个复杂的空间曲线上进行。 顶推时将全桥连接成一个全长380m
15、的连续梁。顶推完成后再将其切断，松去临时连接预应力束，分成三连三跨连续梁。 全桥共分成30个节段顶推，每段长约14m或78m。 整个桥梁的施工过程如图2所示。（节段施工程序）30模场地选择设计资材后方支承测量、平整场地、道路设备导梁拼装墩顶排水临时支座底板钢筋底桩外支座顶临时支承内模桥面板钢混凝土灌注，养生三向预应力顶 推导梁制作间模型板连接部分连结张拉压浆栏杆就位模缩缝路檐石场地整理完成 (预备、临时设施) （主梁制作顶桩） （支座设置） （附属工程）图2 施工流程图 二、顶推设施 1.顶推装置按照本桥上、下行线的最大设计顶推力，每线约700吨，顶推装置的千斤顶如表1所示。表1 顶推千斤顶上行线用涂规格件数设计顶推力张拉千斤顶400吨600st2730吨下行线张拉千斤顶500吨350st2640吨竖直千斤顶400吨50st3水平千斤顶200吨300st2 2.滑动支承 1)构造滑动支承由混凝土制成。分别由各墩台上的最大反力来决究其长度尺寸L，L1000mm为400t用标准滑动支承，L1200mm为550t用。支承表面尽量平整以减小摩擦。滑动支承上面盖有不锈钢板。在梁与其间插入表面贴有聚四氟乙烯板的硬质橡胶滑板。梁的移动在不锈钢与滑板间进行。为了便于活动，滑板长约4060cm。随着梁的前进顺次
